Acclimatization to altitude
|
|
Acclimatization to altitudeThe main cause of altitude sickness is going too high too fast. Given time, the body can adapt to the decrease in oxygen concentration at a specific altitude, process known as acclimatization.
RELATED TERMS--------------------------------------
Oxygen
A chemical element essential for sustaining life.
SIMILAR TERMS--------------------------------------
Acclimation
The process of getting used to a new climate or altitude.
PREVIOUS AND NEXT TERMS--------------------------------------
Accessory digestive organ
An organ that helps with digestion but is not part of the digestive tract. The accessory digestive organs are the tongue, salivary glands, pancreas, liver, and gallbladder.
Accessory dwelling unit
(ADU) A separate housing arrangement within a single-family home. The ADU is defined by Medicare as a complete living unit and includes a private kitchen and bath.
Accessory nerve
The eleventh cranial nerve, which emerges from the skull and receives an additional (accessory) root from the upper part of the spinal cord. It supplies the sternocleidomastoid and trapezius muscles. The sternocleidomastoid muscle is in the front of the neck and turns the head. The trapezius muscle moves the scapula (the wingbone), turns the face to the opposite side, and helps pull the head back. The accessory nerve is so-called because, although it arises in the brain, it receives an additional (accessory) root from the upper part of the spinal cord. Damage to the accessory nerve can be isolated (confined to the accessory nerve) or it may also involve the ninth and tenth cranial nerves which exit through the same opening (foramen) from the skull . Accessory neuropathy (nerve disease) can sometimes occur and recur for unknown reasons. Most patients recover. Paralysis of the accessory nerve prevents rotation of the head away from that side and causes drooping of the shoulder.
Accessory neuropathy
Disease of the accessory nerve which is the eleventh cranial nerve. The accessory nerve supplies the sternocleidomastoid and trapezius muscles.

Accessory placenta
"An extra placenta separate from the main placenta. Also called a succenturiate or supernumerary placenta. The placenta is the organ joining the mother and fetus, the organ that permits the provision of oxygen and nutrients to the fetus and the release of carbon dioxide and waste products from the fetus to the mother. The word ""placenta"" means a flat cake. The main placenta is disk-shaped and at full term measures about 7 inches (18 cm) in diameter and a bit less than 2 inches (4 cm) thick. The upper surface of the placenta is smooth while the under surface is rough. The placenta and the fetal membranes are the afterbirth."

Accoucheur
French for a male obstetrician, a physician skilled in the art and science of managing pregnancy, labor and the puerperium (the time after delivery).
Accoucheuse
"French for a woman who is an obstetrician (a physician skilled in the art and science of managing pregnancy, labor and the time after delivery) or a midwife (today a non-physician trained to assist a woman during childbirth). The ending ""-euse"" is feminine and indicates that the accoucheuse is a woman."
ACE (angiotensin converting enzyme)
The angiotensins are peptides (substances smaller than proteins) that act as vasoconstricting agents (causing blood vessels to narrow). Narrowing the diameter of the blood vessels sends up the blood pressure. ACE converts angiotensin to its activated form (called angiotensin II) enabling it to function. The ACE inhibitors are drugs that inhibit the formation of angiotensin II and are used for blood pressure control and congestive heart failure. The ACE inhibitors include benazepril (brand name: Lotensin), captopril (brand name: Capoten), lisinopril (brand names: Zestril and Prinivil), quinapril (brand name: Accupril), and ramipril (brand name: Altace).
ACE inhibitor
A drug that inhibits ACE (angiotensin converting enzyme) which is important to the formation of angiotensin II. Angiotensin II causes arteries in the body to constrict and thereby raises the blood pressure. ACE inhibitors lower the blood pressure by inhibiting the formation of angiotensin II. This relaxes the arteries. Relaxing the arteries not only lowers blood pressure, but also improves the pumping efficiency of a failing heart and improves cardiac output in patients with heart failure. ACE inhibitors are therefore used for blood pressure control and congestive heart failure.
ACE2 (angiotensin converting enzyme 2)
An essential regulator of heart function. Also may be involved in the embryonic development of the heart. The ACE2 gene has been mapped to the X chromosome (band Xp22).
